Value Collection R57001075 Hex Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R57001075 is a hex socket cap screw designed for fastening applications requiring a recessed drive and high corrosion resistance. Featuring a 1/2-13 UNC thread size and a 5.5-inch length under head, this fastener is driven with a 3/8-inch hex key. Constructed from 18-8 stainless steel with a bright uncoated finish, it delivers solid mechanical strength and resistance to rust and oxidation in exposed or wet environments. This type of fastener is commonly installed by machinists, pipefitters, millwrights, and maintenance technicians working in industrial, commercial, or marine settings.

This hex socket cap screw is suited for use in equipment assemblies, structural fixturing, machinery frames, and other applications where a flush or recessed fastener head is required. The 1/2-13 UNC thread profile is a coarse-thread standard appropriate for general-purpose fastening through metal, plate stock, or tapped holes. The 18-8 stainless steel construction makes it a practical choice in environments where mild chemicals, moisture, or salt air are present.

Key Features

• 1/2-13 UNC coarse thread for reliable engagement in standard tapped holes
• 5.5-inch length under head accommodates thicker material stacks and deep-reach applications
• 3/8-inch hex drive provides solid torque transfer with standard hex keys or socket drivers
• 18-8 stainless steel construction resists corrosion in wet and mildly corrosive environments
• Bright uncoated finish — no surface treatment to interfere with dimensional tolerances

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw suitable for use in any tapped or through-hole application requiring this thread size and length under head.

Installation Notes

Installation is performed using a 3/8-inch hex key or socket driver. Always confirm the mating thread is clean and free of debris before driving. Apply appropriate thread lubricant or anti-seize compound when fastening stainless steel into stainless steel to prevent galling. Follow applicable torque specifications from your engineering documentation or applicable code references for the assembly type.
